My shift knob on my 1998 S500 is fading and I was looking into a new one.I found this knob on Ebay (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8060888775&ssPageName=MERC_VI_RSCC_Pr4_PcY_BIN_Stores_IT) and it looks good to me.My question is,will this fit over my original shifter and is it a DIY job or a dealer?How much will a dealer run me for it.Thanks
